Which fall protection is suitable for floor-to-ceiling windows? Advantages/Disadvantages

Hello,

we are currently completely unsure about the fall protection for our floor-to-ceiling windows.
Originally, windows with built-in separation and fixed glass at railing height were planned.
Currently, my wife has become enthusiastic about a modern French balcony.
However, the enthusiasm was significantly less when we saw the high price of the stainless steel grilles.
Now we are facing a dilemma.
What are probably the advantages and disadvantages of the two options?
What would be the approximate additional cost for the lower fixed glazing compared to the French balcony?

Purely an aesthetic preference. Prices are set by the GU.

I wouldn’t put any grilles in front of the windows, rather I would forgo the floor-to-ceiling craze on the upper floor.

We have floor-to-ceiling windows with a fixed glazed lower part on the upper floor. The disadvantage I see is that in summer you have to raise the shutters above the fixed glazed part to let air in. And accordingly also brightness. With the variant with a French balcony, you only need to open part of the shutters to let air in. Depending on how you react to brightness, this may need to be considered.

French balconies can also be made of galvanized steel, which should be considerably cheaper than stainless steel.

I see a cleaning problem for myself with a lower fixed glazing. How is one supposed to properly clean the windows, the frame, and the windowsill from the outside? That is why we decided on French balconies made of stainless steel, we also like them very much aesthetically.

Best regards
Sabine

We would like a fixed glazing on the windows for aesthetic reasons... in the recess or whatever it is called. So not attached to the side masonry.

However, at the moment we rather have the problem of finding someone who will actually do it that way :-(

Well, I only see the cleaning problem to a limited extent. If you make a bit of an effort or have suitable cleaning materials, it’s actually quite easy. We currently have the same thing in our rental apartment. Each balcony or railing is also cleaned from the outside like this. Or hire a cleaner 3-4 times a year.

Ventilation is rather less of a problem, as we currently have a central supply and exhaust ventilation system planned.

The annoying issue is of course the acquisition costs. For the railings, the general contractor would charge about 500 euros per railing, and I find that a bit excessive. So now my question to the people who have a two-part floor-to-ceiling window with a fixed lower section.
What additional costs did the whole thing cause in relation to the "normal" casement window?
